Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact contact plating thickness and flange dimensions. Ensure the selected variant matches the required board thickness tolerance of 1.57 mm. Confirm RoHS3 compliance status through the latest product documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, high-density connection is required for thick PCBs. The 3.96 mm pitch accommodates larger traces compared to finer pitches. Verify that the panel mounting style aligns with the mechanical enclosure design. Ensure the 5 A current rating meets the circuit requirements for all active lines.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers a range of card edge connectors with varying position counts. The series is characterized by robust construction suitable for harsh environments. Similar models in the series include 305-050-520-203 and 305-054-556-278, differing primarily in contact count and specific flange configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-048-520-502, which shares identical electrical and mechanical specifications. Cross-series replacements require verification of pitch, row count, and mounting style compatibility.
